COME-INED CHIMNEY AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 340,379, dated April 20, 1886.

Application filed January 2S, 1886. Serial No. 190,058. (No model.)

To @ZZ whom t 'may concern.'

Be it known that LSAMUEL W. Siiirwon'rH, a citizen of the United States, and a resident of Blue Mound, Linn county, Kansas, have invented certain Improvements in Combined Chimneys and Ventilator-s, of which the i'ol lowing is a specifica-tion.

My invention relates to that class of com' bined chimney-dues and ventilators in which the Ventilating-flue surrounds the smoke-Hue or chimney, my invention comprising certain details in the construction of a device of the this class with the view of rendering it effect ive in action, simple in construction, and readily applicable to the building in connection with which it is to be used.

In the accompanying drawings, Figure l is a sectional View of a building provided with my improved chimney-flue and ventilator; Fig. 2, a perspective view ofl parts of said chimneyflue and ventilator detached from each other, and Figs. 3 and 4 detached sections of the up per part of the device.

I have shown my invention in the present instance as applied to a house having two stories and an attic; but it will be evident that it may be varied in size to suit houses of dif` ferent constructions.

The ventilator is made in three sections, A, B, and D, the upper section, A, being above the roof, and having an outer casing, c, which may be square-or of other suitable form, and painted in imitation of an ordinary brick chimney, and this casing should have at the lower edge a projecting plate, b, which is so secured to the roof of the house as to forni a watery-tight joint.

The section B consists of a cylinder, (l, having at the top a projecting plate, e, also conn'ned to the roof, said cylinder passing down through the attic and. upper rooms of the house, and being constructed at the lower end for the reception of the outer cylinder, f, of the lower, section, D, of the ventilator, this section passing through the door and ceiling and terminating in the lower room or apartnient of the building.

The upper section, A, of the ventilator has a dat top, to which is connected by a watertightjoint the upper end of the smoke-flue g,

which passes down through the lcasing a and cylinder d, and receives at the lower end the upper end of a pipe, h, forming part of the lower section, D, of the ventilator.

smoke and products of combustion from stoves or furnaces located in the various rooms of the building, (see, for instance, the dotted lines in Fig. 1,) while the annular chamber or space between said smoke-due and the outer casing of the ventilator provides for the passage of foul air from the various rooms, this foul air entering the annular space or chamber through suitable valved ventilators, and escaping through openings t' at the upper end of the casing c into a chamber formed within the molding m, surrounding the upper end of said casing, from which chamber the air escapes through openings a at the bottoni.

rlhe upper section, A, of the ventilator has at the top an arched hood, F, to prevent the entrance of rain or snow directly into the mouth of the flue y, and to prevent rain or snow fromdriving in from either end of said arched hood, the latter has at each end inclined detlectors p, as shown in Fig. 3, these deflectors forming with the hood contracted airspaces s, which serve to direct forcible blasts of air across the hood and in contact with the inner face of the same, so as to prevent the accumulation of soot thereon.

In order to permit access to the flue g, for the the purpose of cleansing the same when necessary, the hood F is hinged at one edge and confined at the opposite edge by a locking pin or key, so that on removing said key the hood can be readily thrown to one side, as shown in Fig. 2, and the mouth of the Hue exposed.

By making the ventilator in sections, as described, the manufacture of the same and its application to a building are facilitated, the telescopic joint formed between the sections B and D of the ventilator and between the fine-pipes g and It permitting the application of the ventilator to houses which vary slightly in the height of the stories, without a special construction of device for this purpose.

I am aware that a ventilator has been proposed in which the upper part of a lower section is fitted into the lower end of an upper The central ilue thus provides for the escape of the W section; but in this case telescopic movement l roofplate b, the section B, consisting of a tube,

was prevented, owing to the fact that the lower section had a top or cap plate extending from the inner to the outer tube, which capplate came into contact with the lower end of the inner tube of the upper section. In my iinproved ventilator there is no such obstacle to the free telescopic movement of the lower section of the ventilator in the upper section.

I claim as my inventionl. The combination, in a combined chimney and ventilator, of the following elements, namely: the top section, A, consisting of a casing, a, the roof'plate b, and the smoke-due y, secured to the top of the casing, the in termediate section, B, having a roof-plate, eand tube cl, inclosing the ilue g, and the lower section, D, having two tubes, f and 7i, forming a telcscopicjoint with the tube d and flue g, all substantially as specified.

2. The combination ofthe top section, A, of

the ventilator, consistingl of a casing. a, and

d, with roof-plate e, and the smokeue g, secured to the ltop of said upper section and projecting down through the tube d, all substantially as specified.

3. The combination of the top section of a ventilator and the smokefiueg with the arched hood F and the inclined detlectors p at the ends of the same, all substantially as specied.

4. The combination of the top section, A, and its smoke-flue g with the arched hood F, having at its ends inclined deectors p, forming contracted air-passages immediately be neath the hood, all substantially as specified.

In testimony whereof I have signed my name to this speciication in the presence of two subscribi ng witnesses.
